Definitions

  • the present invention relates to a cellular concrete construction block coated, covered or otherwise wrapped with a thickness of plastic material. It is intended to be used in the field of the building to realize walls, walls and partitions, houses, various shelters, garages, any buildings or any other type of construction by embedding and / or collage several building blocks.
  • Cellular concrete building blocks have been known for a long time and are intended to be juxtaposed and glued together for the construction of walls and walls.
  • these monolithic cellular concrete building blocks are unsightly, and are likely to absorb moisture if wet. In addition, they are difficult to plaster, coat or paint and are more sensitive to impact than bricks and concrete blocks. Therefore, these blocks are not always compatible with a construction exposed to climatic conditions and bad weather, and that one wishes to see to last many years.
  • these cellular concrete building blocks must be painted or coated with an external coating or plaster, at least on their outer face, to provide a satisfactory aesthetic appearance for the facade, which represents an additional cost in the realization of constructions made from these blocks.
  • These surface treatments are also difficult to achieve due to the presence of dust and surface aerated concrete powder, which also increases their cost.
  • the exterior walls of the current constructions are traditionally made by stacking brick-type building elements, blocks, concrete blocks, blocks of stone, concrete block or other similar elements, which are immobilized between them by the application of a layer of cement or mortar.
  • the object of the invention is to propose an alternative to these traditional building elements by providing a building block mainly of cellular concrete and plastic material, intended to be assembled with other similar building blocks and which does not have the defects of existing building blocks.
  • An advantage of the building block according to the invention is obtained by the combination of the characteristics of cellular concrete and the advantages of a plastic envelope to manufacture blocks for the realization of insulating walls in the field of construction including dwellings.
  • the aim assigned to the invention is achieved by means of a building block, having an inner main face, an outer main face, an upper face, a lower face, and two end lateral edges, said block of construction comprising at least one rigid body and at least one plastic envelope at least partially enveloping said rigid body, characterized in that the rigid body comprises at least one mass of cellular concrete or mainly of cellular concrete.
  • At least one plastic envelope may also fully enclose said rigid body.
  • the block according to the invention has the advantage that a "low-pressure overmolding" can be used to coat the rigid body of cellular concrete or mostly cellular concrete with a plastic material.
  • a "low-pressure overmolding" can be used to coat the rigid body of cellular concrete or mostly cellular concrete with a plastic material.
  • an overmolding pressure of between 30 and 200 bar was sufficient with the use of cellular concrete.
  • An alternative solution for example consisting of first forming a plastic shell in which the cellular concrete is inserted may also be considered.
  • the rigid body is mainly of cellular concrete, coated, overmolded, dressed or otherwise wrapped with a thickness of plastic material which gives the final block its external shape with precise dimensions and its aesthetic and protective characteristics .
  • the sharp angles and the flatness of the faces are thus obtained by coating, overmolding, wrapping or wrapping the cellular concrete with the plastic material.
  • the latter makes it possible to obtain a satisfactory exterior rendering of finish and protection.
  • Recessing structures may be provided on certain faces of the building blocks according to the invention, especially on the lower and upper faces, to allow easy, fast and reliable positioning and assembly. They can only be joined together with glue, applied with a simple applicator or a glue gun, which allows them to be easily and quickly set up even by non-professionals.
  • the inner and outer faces of the building blocks can receive a coating, a decor or a treatment directly during the coating step, during the overmolding step or during the step of wrap, which gives them a remarkable aesthetic rendering and substantially improves their protection. Moreover, this reduces considerably the price per square meter of walls and walls due to their direct use.
  • the blocks of the invention being covered with a layer of plastic material, their service life is high and it is no longer necessary to coat the outer and inner faces of the walls and walls thus erected. It is therefore a lightweight building block, inexpensive and having good characteristics of strength and thermal insulation. It is easy to use and requires no maintenance. In addition, its visible faces are decorated during manufacture and any subsequent step of applying an aesthetic coating becomes superfluous.
  • the building blocks according to the invention are protected against external conditions and do not fear moisture.
  • the building blocks according to the invention are resistant and have virtually no thermal expansion.
  • the phenomena of expansion and shrinkage of the walls are overcome by the action of the variations of the ambient temperature and consequently the deformation thereof, without the need to provide expansion joints.
  • the invention also relates to a construction of the wall, partition or wall type comprising an assembly by bonding and / or embedding of building blocks according to the invention one after the other and / or on each other so that their upper and lower faces and / or their end side edges are in mutual contact, so that the two main faces of each block respectively form part of the inner and outer faces of the wall, wall or wall.
